BasicStudents matched to this level have a partial mastery of prerequisite knowledge and skills fundamental for proficient work.

At Grade (Proficient)Students matched to this level have demonstrated competency over challenging subject matter, including subject matter knowledge, application of such knowledge to real-world situations, and analytical skills appropriate to subject matter.

AdvancedStudents matched to this level are ready for material that requires superior performance and mastery.

Nine question quiz. Students must examine diagrams of triangles and the coordinates of triangles and determine if they are congruent using the SAS congruency theorem. Students must justify their reasoning. Students must also draw (on the coordinate plan) an example and non-example of triangles that can be proven congruent using the SAS theorem and then explain their reasoning.

This study guide is an overview of triangle congruence: defining corresponding parts of congruent triangles, postulates and theorems for congruences (SSS, SAS, AAS, ASA), and postulates and theorems for congruences for special triangles.
